Replacing the Print Mechanism
See “Removing the Print Mechanism and PC Board Assembly” for more information.
1. Lift the entire mechanism/board assembly and place it in the cabinet.
The mounting shelf (in the rear of the mechanism) should fit under the row of ribs
along the back inside of the cabinet. The front of the mechanism assembly should now
drop into place.
2. If necessary, gently push the front corner of the PC board closest to you.
The assembly is correctly positioned when:
• The PC board is in its guide slot at the cabinet bottom
• The printer mounting hole is lined up with the screw hole on the bottom
• The printhead cable is inside the cabinet and is not protruding through the bottom
3. Hold on to the entire cabinet assembly and turn it over.
4. Replace the bottom screw and tighten gently.
Do not overtighten.
Finishing Up
Replacing the L-Cover
See “Removing the L Cover” for more information.
1. Attach the ground strap to the PC board.
2. Position the cover, taking care to align the buttons with the switches underneath.
3. Push on the left corner until that latch snaps.
4. Carefully push out on the inside back of the cabinet with your left hand, while pushing
down on the L cover with your right hand.
This will snap the L cover into position.
Replacing the Receipt Cover
See “Removing the Receipt Cover” for more information.
1. Hold the top cover vertically over the hinge brackets in the printer cabinet.
2. Align the hinges.
3. Push down gently until the cover snaps into place.

bottom of the bin toward the printhead area.
